Coca-Cola and SeaWorld Parks & Entertainment expect SeaWorld's switch to PlantBottle plastic in its refillable cups to remove 35 metric tons of CO2 emissions annually, the companies say. The recyclable cup, using Coke's sustainable packaging technology, is now available in all SeaWorld and Busch Gardens parks across the U.S.

Using PlantBottle technology, SeaWorld has created the first commercially available consumer product: a refillable plastic cup.

Since Coca-Cola introduced PlantBottle technology in 2009 as the first recyclable PET plastic bottle made partially from plants, more than 450,000 barrels of oil reportedly have been saved. And, more than 20 billion PlantBottle packages have been distributed in 31 countries worldwide.
